Hi Emm,
Keep an eye on that, it's a possible sign that there might be too much in the band. Fluids especially water should never come back up, even after a fill.
If it does not settle in 48 hours, call provider and ask for 1/4 or half mill out, and this can make all the difference.
Hope it settles soon, as a band that's too tight is as useless as a band that is too loose.
